My invention relates to improvements in window construction and the mainobject is to provide aneilicien't, durable, and non-rattling meta!window sash and frame having ,5 also a number of other features ashereinafter fully set forth, reference being had to the accompanyingdrawings, in which,'--l

Fig. 1 is an inside elevation of m improved window, in a four-pane typean hinged at one side a .so-called easement window.

Fig. is a horizontalV cross sectional view about as o1. line 2-2 in Fig.1.

Fig. 3 is an enlarged sectional perspective a single glaze type of sashand window channel of my improved type and includin a certain metal clipfor retaining the edge or the glass.-

Fig. t is an elevation of preferred window pane retaining bars for atour-pane type of 4window as illustrated in Fig. 1.

. Fig. 5 is a perspective, 'enlarged detail oi a channel type `.muntinbar used with the retainin bars shown in Figs. 2 and 4.

Fig. 61s a cross sectional detail of the u per bar of my window sash, ina modified orm adapted to be hinged at the lower frame bar and includinga manually released' spring operated latch device.

Fig. 7 is a cross section of an I-beam shaped muntin bar 'fordouble-glaze windows and Fig. 8 is a cross section of a preferred typeof hollow muntin bar used in single glaze windows of my improved type.

355 tion of the muntin bar shown in Fig. 8, look- --are in quadran Fig.9 is a front oi' face view of an end pors ective view or a corner of oneof the winow-sash shown in Fig. 11.

Fig. 12 is an elevation of the quadranguf larly arran ed pane retainingframe members as use inthe types of windows shown a0 in Figs. 10, 11 and13.

.Referring to the drawings by reference numerals it will lirst beunderstood that l aim to provide an all-metal window frame, usually ofcourse uadrangular and embodya ing suitably joine lates 15'to thevertical ones of which may lib fixed elongated metalv sash-weightpockets 16. 17 in Fig. 1 illus- .trates face boards or plates ofsuitable size t and extending. from main frame 15.

18 are metal channel members suitably fixed by welding, or otherwise, tothe vertical frame members 16, in pairs as in Fig. 10 for two-sashwindows or in single continuous @5 quadrangular formation as in Fiss. 1and 2 for hinged sash. In all types of windows embodying my improvementsthese channels have an outer wide flange 18A and an inner narrow, ange18B. lin the sliding sash type 70 of windows these channels are therunways for the sash and in the easement type they lar formation and thesash swung into position within the uadran lar channel frame as willpresently e described. The swin 'ng type wil be first described.

n comination with the stationary means just described my improved windowcom-- prises further, a metal sash, single or double, and a certain typeoi storm sash, the latter a0 embodying certain pane retaining featurescommon to all types of sash herein described.

ln Fi 1 l have illustrated a horizontally swingab e four pane singleVsash A hinged at 184: to the main frame 15. lin this sash iframe a5 andthe modification thereof in other views4 the general designation A willbe used and variations in details designated likewise with numericalsuiiixes, for a more ready understanding of its construction. w

e outer edges of the @u 4 shoulder A4 in vertical of the inner part or'this ledge is formed a The sash A is of course quadrangular being formedof 4 quadrangularl arranged suitabl joined (as by welding sash bars,each of ormation, in cross section, comprising an ,outwardlydirectediange A1, anA inwardly adjacent continuous groove A2, in theinner part of the latter is a continuous ledge A3 and continuinginwardly from'this ledge a continuous central, hollow ridge or rib A5(see Fig. 3) from which the metal is shaped to extend inwardly incertain, modified ways and terminates in an inner outwardly directedange A6 in vertical plane, said latter flange adapted to bear againstthe inner ange of flange 18B of the iixed channel `'rame 18simultaneously as the sash flange the ed e of channel ig. 3) w en theswinging sash (of Fig. 1) is closed, said flange A1 overlapping as shownbest in Fig. 3.

19 are fixed, crossed muntin bars in the A1 engages lightl ilange 18A(as in i sash,for a four pane sash frame (see Fig. 1)

bars are kept apart each with its ends suitably fixed in opposite ridgesA5 of a sash. Thesevbars are illustrated as shallow channel irons, inFig. 2 and Fig. 5 the opening of the channel being toward the glass andto receive putty or other glazing flush or little outwardly of thechannel for the glass 20 to bear against. The adjacent edges of thepanes at said muntin by fixed parting lugs 21 in said channels eachhaving a projection 21P to register with openings 22? of crossed paneretainin metal bars 22 bearing toward the face of t e glass by havingtheir ends slidably inserted and` sprung into grooves A2 of the meh rs A(see Figs. l, 2, 4 and 5) ln a single pane type of sash (as in Fig. 2)the glass 20 is cut in a size permitting 1t to be passed inwardlybetween anges A1 of the sash bars and against shoulder All after whichputty as 23 is filled in the groove A2 to retain the glass. .2A is a datspring metal clip formed with a ledge 24A adapted to rest on shoulder A3thence curved up in a Asemi-circular hump and extended down thence toengagein the front, lower part of groove A2.` The humped part isfrictionaly engaged by the edge of the glass (see Fig.

3) and it will be .understood that each vclip is retained slightlycompressed in the groeve and ledge parts as shown, the clips being inserted in predetermined spaced relation before puttyor the .like isapplied, the clips being of course entirely if... nidad.

In Fig. 6 is shown, in cross section, an`

upper bar' of a sash hid at its lower edge, such as a transom sash.rlhis is a double glaze sash with modified bar section and includes aspring metal latch `bar`25 xed at 26 on the inner part of ledge A3extending upward angular-1y (normally) thence plane and inwardly sashfrom their grooves,

Lacasse down, at 25S, angularly and outwardly through an aperture 27 inthe bar, outwardly of which it is' formed with a loop 25L or othersuitable engaging means. The part 25S normally is pressed upward againstand pinches the flange 18B of channel 18 thus holding the sash sash isreleased by simply pulling down loog 25L so the spring `can pass underflange 18 and permit the sash to be swung open asin direction of arrow28. In thisv double glazed sash the groove A2 is narrow and deep andledge A3 comparatively wide. rEhe muntin bar is an I-beam in crosssection (see also Fig. 7) and inwardly of the rid e A5 an inner edge A3is formed for t e inner pane 20.

In this case groove A2 forms a continuous quadrangular pocket forretaining respectively an upper iiat metal retaining bar 29, oppositevertical' bars, 29B and a bottoni bar 29C, (see also Fig. 12) all of awidth to project inwardly toward the center of the and between whichprojecting parts and the pane, puttyis inserted (best shown in Fig. 6)For retaining the inner pane, vlike bars 29, 29B and 29C are used butmay be secured as with screws 30 to 'the sash bar.

19B in Figs. 8 and 9 illustrates a hollow, rolled metal muntin bar, asan alternative for 19, and for single pane sash only,`said bar beingapproximately triangular in cross section and having a vertical face foradjacent pane sections to bear against. In said vertical face is a lon'tudinal slit 31 widened at .its ends at 31A or insertion of a nut'32and screw 33 provided in suitable numbers and adapted to engage inapertures 'of a glass retainin bar 22B which thus covers the adj acent eges of the anes and may be clamped against the glass y said screws.

In the forms of window sash above described I have disclosed'single sashconstruction only, I will now describe double sliding sash as inordinary house construction, where there is an u per and a lower sashslidable in parallel p anes, this being done inl my improved windowdevice-by providing in each frame 2 fixed channels 18 on oppositevertical members 16 of the main frame. The adjoining bars of the twosash must of course come to parallel, horizontally registering ositionswhen the window is closed, as in ig. l1, where double glazed sash areshown but single glazed equally adaptable.

' n these horizontal bars I provide a hollow bar construction forweather proof construction',embodlying the barA as described but to eachof w ich is fixed asat v34 a horizontal channel corresponding 4to theixed 4channels 18 of the mam iframe. -lhe upper rigid when closed. Thelmemb their front and rear anges are cut away at the ends and the webscontinued to fit slidably and transversely in the main frame channels18, as at 36 in Fig. 13. 37 is a metal plate secured on either or bothbars 35, as on the right hand bar inFig. 11, said plate overlapping aportion of the adjacent sash cross bar to provide a weather proof jointat W. 38 are apertures in the guided end web parts of the bar througheach of which a sash cord 39 extends upwardly from any suitable cordattaching means such as the fixed eye-bolts 40 (Fig. 10) in the verticalsash ers A.

It will now be readily understood that my invention embodies a metalmain frame with integral elongated inwardly opening channel membersbetween which is the space occupied by either sliding or swinging sash,the latter kind involving, selectively, sash hinged at either side, topor bottom. Further, means are provided in the making of the sash barsfor either single or double glass and in Fig. 2 is illustrated a stormsash mounted within the main frame, whether fixed or hinged.

In said storm sash, Fig. 2, the glass 2O is retained in sash bars 41 ofapproximately but distorted S-shape in cross section having an outer,inwardly opening glass receiving groove 41G corresponding to groove A2(Fig. 3). Inwardly of the glass retaining groove the frame is formed asa continuous vertical. flange 1F movable inwardly to stop positionagainst the outer flange 18A of the main frame channel. rIhe thicknessof sash bars of said storm sash is such that it may be inserted slidablywithin and between the parallel channels 18 to serve as a sliding sashtherein.

In Fig. 2 I have also illustrated, on the left upright sash member a cam42 on a pin 43 having a hand operated lever 44 accessible inwardly ofthe window to swing the cam into engaging position inside of the channelflange 18B and thus hold a easement window closed positively.

Ll5 in Fig. 10 are upright interior bars in fixed parallel relation toeach upright fiange A6 of a sash to provide vertical guide means for theslidable sash.

I claim In combination, a window sash comprising a quadrangular frame ofjoined metal bars,

ridge formed in each bar inwardly of said groove, muntin bars fixed withtheir opposite ends in said ridged parts of the sash bars and means forholding panes of glass in the sash with .their adjacent ed es at themuntin bars in spaced relation an removable auxiliary muntin barsarranged to lie over said adjacent edges of the panes, the outer ends ofsaid auxiliary bars adapted to be removably engaged in the grooved partsof the sash bars.

In testimony whereof I aix my signature.
